THE LOWEST-NOISE DRIVER AVAILABLE
These Low Noise QCL Drivers have the lowest current noise density of any commercially available driver. Powering your QCL with this patented driver will enable better performance—at lower cost and in less time—than otherwise possible.

This is the right driver for lasers that require a high-precision and ultra-low noise current source. The 500 mA QCL laser driver exhibits noise performance of 0.4 µA RMS to 100 kHz, and an average current noise density of 1 nA / √Hz—the lowest available today.

CHOOSE THE RIGHT OUTPUT CURRENT RANGE
The QCL Driver family is available in four different models so that you can choose the ideal one for your application:

We can modify the driver at the factory to suit your particular QCL application.
* For example, the standard maximum compliance voltage is 16 V. For up to 20 V compliance, request Product Variation PV055.
* For higher efficiency operation at ±15 V (compliance voltage of 7 V), request PV066.

* OEM versions — loaded PCBs only — are also available.

ULTRA-NARROW QCL LINEWIDTH
In order to maintain their characteristically tight center linewidths and minimize jitter, quantum cascade lasers must be powered by drivers with exceptionally low current noise density. Our customers have reported achieving narrower linewidths with these drivers than any other they’ve used.

HIGHEST MODULATION BANDWIDTH
The high modulation bandwidth and fast rise-time maintains modulation waveform integrity so you can shape the laser output profile exactly as your application requires.

DESIGNED FOR RAPID INTEGRATION
The robust design and simple operation of our drivers allows you to take your revolutionary QCL application from the test bench to market quickly and efficiently, using the same driver throughout the entire process. You can focus your efforts on the demanding technical aspects of the system.

PROTECT YOUR QCL INVESTMENT
All the essential control and monitor functions you expect in a Wavelength laser driver are incorporated into this driver, along with protection circuitry to safeguard your QCL from minor power source faults, over-temperature conditions, and electrical faults. The soft-clamp current limit features a brick-wall never-exceed characteristic that prevents the QCL from being accidentally over-driven and damaged.

KNOWLEDGEABLE CUSTOMER SERVICE
